1 - Start playing from the music library.
2 - Switch to the Cover art browser and wait until it loads completely (the error doesn't seem to happen while the source is loading).
3 - Double click on any album cover.
I'm able to reproduce the error almost 100% of the times, but I haven't figured out why it doesn't happen sometimes.
